Boat is a Nauta 54' of Kaufman 1989.
rig, 23tonnes, in the sail plan I = 22m or 73'.
I got rid of 2furling gear
, which I hate.
I plan for an Olympic jib
95%, staysail, yankee 65% storm jib
Question: I feel like I need a JIB
4 for some upwind (60degrees...) in heavy conditions, say F7-8, where the Yankee 65% is too large and less effective...
Some say size is 13.5% of I2 (squared) in so far a storm jib
is anything between 3,5 to 5% of I2....but 40+sqm sounds too large to me
In said conditions, 23tonnes displ. 9Tonnes ballast, 8'draft... is there a formula to calculate how large a Jib4 can be?
I mean, the maximum bearable Upwind jib without mainsail
, but NOT a storm jib yet...
